Swift：“ViewController.Type”没有名为“URL”的成员

Question

我的视图控制器中有一些代码

 var URL: NSURL = NSURL(string: "http://someurl.com")!
 var request : NSMutableURLRequest = NSMutableURLRequest(URL:URL)

 request.HTTPMethod = "POST"

 var bodyData = "data=something"


 NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue())
    {
        (response, data, error) in
        println(NSString(data: data, encoding: NSUTF8StringEncoding))
    }

但是我收到错误：“ViewController.Type”没有名为“URL”的成员。如果我将代码放在 ViewDidLoad 中，它适用于应用程序启动。

如何让代码在单击按钮时运行？我尝试将@IBAction 放在 ViewDidLoad 函数中，但这也不起作用：/

@IBOutlet var serverLabel: UILabel!

@IBAction func serverButton(sender: AnyObject) {


}


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.


}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}

您的代码都没有在方法中，将其包装在方法中并在适当时调用该方法。
